Question

Re-write the equation 3x - y = 4 in slope-intercept form.

a. y = 3x -4
b. y = 3x + 4
C. y=-3x
D. y=-3x+4

Answer 1

a

Explanation:

The equation of a line in slope- intercept form is

y = mx + c

Rearrange 3x - y = 4 into this form ( add y to both sides )

3x = y + 4 ( subtract 4 from both sides )

3x - 4 = y OR y = 3x - 4 → a
